The insertion openings 168 are preferably used to insert the connecting sections 188 arranged at the projections 187 or tabs 186 of the first connecting body element 140 (see FIGS. 15 and 16).

On the side of the base plate element 174b facing the connection projections 178, the insertion openings 168 of the second connection body element 142 preferably likewise comprise one in particular

circumferential chamfer 170.

Otherwise, the second connecting body element 142 is identical in terms of structure and function to the first connecting body element 140, so that reference may be made to the description thereof insofar. The reinforcing element 146 and the adapter element 148 are not shown alone in the figures, so that reference is made to FIG. 1 for their description.

The reinforcing element 146 can be pushed onto the bearing receiving part 154 of the first cover element 134 to reinforce the first cover element 134 and, for this purpose, preferably comprises a plug-on opening 190. The plug-in opening 190 is preferably designed as a passage opening.

The driving profile 202 of the torque transmission element 150 is preferably arranged concentrically to the axis of rotation 121 in a radially inner region of the connecting body 138.

The torque transmission element 150 is preferably rotatably coupled or rotationally coupled to the adapter element 148 by means of the carrier profile 202 (compare FIGS. 2 and 3).

Preferably, therefore, a torque and / or a rotational movement can be tapped via the adapter element 148 at a radially inner region of the connecting body 138, wherein a rotation of the two cover elements 134, 136 to each other, which are connected to the connecting body 138 at a radially outer region , can be reduced.

In the present case, however, the abovementioned components are in particular caulked with one another.

Such caulking for producing a rotationally fixed and / or torque-transmitting connection of a first component 208 and a second component 210 will be described and explained in more detail below with reference to FIGS. 19 to 29.

FIGS. 19 and 20 show a first component 208, for example the first connection body element 140, and a second component 210, for example the first cover element 134, in an undeformed state of the two components 208, 210, in particular prior to caulking of the two components 208, 210.

FIGS. 21 and 22 show the first component 208, for example the first connection body element 140, and the second component 210, for example the first cover element 134, wherein at least the first component 208 is partially deformed. In particular, FIGS. 19 to 22 show a first exemplary embodiment of a method for producing a rotatable and / or torque-transmitting connection.

In the second component 210, an insertion opening 168 is preferably introduced in the form of a passage opening, which comprises an at least approximately rectangular opening cross-section.

The insertion opening 168 preferably comprises a peripheral edge region 212.

In particular, the insertion opening 168 comprises at least one, preferably two, pairs of edge regions 214 lying opposite each other, in particular parallel to each other.

The connecting portion 188 of the first member 208 preferably includes two deformation portions 216 which are spaced apart from each other.

The deformation sections 216 are preferably formed as deformation webs 218.

Preferably, the deformation sections 216, in particular the deformation webs 218, can be deformed by means of a tool 220 (see FIGS. 27 to 29) which, for example, is moved in the direction of the arrow 222 in FIG.

The deformation sections 216, in particular the deformation webs 218, are preferably deformed in a forming direction 224 when the tool 220 strikes the deformation sections 216, in particular the deformation webs 218. The deformation direction 224 is in this case in particular perpendicular to a direction of movement of the tool 220 represented by the arrow 222.

Preferably, the deformation portions 216 are reshaped by means of the tool 220 in a single step, in particular in a one-step process.

The deformation sections 216 of the connection section 188 are preferably deformed along the deformation direction 224 such that the connection sections 188 abut against the second component 210 after the deformation sections 216 have been deformed in the deformation direction 224.

In particular, the deforming sections 216 are at least approximately completely over the entire surface after the forming at the two mutually opposite edge regions 214 of the insertion opening 168 (see FIGS. 21 and 22).

Preferably, the deformation sections 216, in particular the deformation webs 218, are plastically deformed during forming. The deformation sections 216 are in particular cold-formed.

During the deformation of the same, the deformation sections 216 are preferably pressed against the two opposite edge regions 214 such that the two components 208, 210 are non-positively connected after the forming sections 216 have been deformed.

As can be clearly seen in FIGS. 21 and 22, the deformation sections 216 are preferably further shaped in such a way that the deformation sections 216 of the connection sections 188 of the first component 208 engage behind the second component 210 at least in sections, so that the two components in particular also positively connected. The insertion opening 168 and the connecting section 188, in particular the deformation sections 216 arranged thereon, are preferably arranged to produce a rotatable and / or torque-transmitting connection such that the deformation sections 216 are deformed during forming in a forming direction 224 which is tangential to a coaxial one Rotary axis, in particular coaxial with the axis of rotation 121 of the gear 104, arranged circle.

Conveniently, the insertion opening 168 and / or the connection section 188 comprise a width which is greater than a length of the insertion openings 168 perpendicular to a desired rotational movement and / or torque to be transmitted. Preferably, a particularly large torque can be transmitted in this case ,

Preferably, a particularly efficient torque transmission from the first component 208 to the second component 210 or vice versa can thus be made possible.

A second exemplary embodiment of a method for producing a torque-proof and / or torque-transmitted connection is shown in FIGS. 23 to 26.

The method for producing the non-rotatable and / or torque-transmitted connection differs from the method for producing a rotationally fixed and / or torque-transmitted connection shown in FIGS. 19 to 22 substantially in that at the connecting portion 188 of the first Component 208 in addition to the deformation sections 216, which are deformed in the forming direction 224, further deformation sections 216 are provided, which are also formed as deformation webs 218.

These additional deformation portions 216 are preferably by means of a special tool, not shown in the figures in a perpendicular to the Forming direction 224 extending and formed by the arrow 226 direction formed. For this purpose, the insertion opening in particular comprises recesses 227 for insertion of this special tool.

As can be clearly seen in particular in FIG. 25, the two additional deformation sections 216 are preferably shaped in two opposite directions along the direction 226 by means of the special tool.

The deformation portions 216 are also in particular plastically deformed.

Preferably, by providing these additional deformation portions 216, a full-surface abutment of the deformation portions 216 on all edge regions 214 of the insertion opening 168 can be made possible, so that the connection portion 188 is supported on all sides in the insertion opening 168.

Preferably, therefore, a particularly reliable connection for transmitting a high torque can be provided.

Incidentally, the second exemplary embodiment of the method for producing a rotationally fixed and / or torque-transmitting connection illustrated in FIGS. 23 to 26 is identical to the first exemplary embodiment shown in FIGS. 19 to 22, so that reference is made to the description thereof can be taken.

FIGS. 27 to 29 show the deformation of the deformation sections 216 in individual steps.

In FIG. 27, the first component 208 is still spaced from the second component 210 by a gap 228. In the case of the deformation illustrated in FIG. 28, this gap 228 is preferably reduced in size. It is conceivable that the gap 228 completely disappears in the case of the deformation shown in FIG. 28, so that the deformation sections 216 abut the edge region 214 over the whole area.

It can clearly be seen in FIG. 29 that the deformation section 216 is embossed by means of the tool 220, so that the deformation sections 216 of the first component 208 at least partially engage behind the second component 210 and, in particular, rest against the edge region 214 over the whole area.

The embossing of the deformation sections 216 by means of the tool 220 can preferably be carried out in a single step after the deformation of the deformation sections 216, in particular in a single-step method.

The two cover elements 134, 136 and the two connecting body elements 140, 142 are preferably connected by caulking on the basis of the method shown in FIGS. 19 to 29 for producing a torque-proof and / or torque-transmitted connection.

Preferably, by means of the planetary receiving device 100, in particular by providing the connecting body 138, a particularly favorable force transmission in the transmission 104 shown in Figure 2 are possible.

For this purpose, FIG. 2 shows in particular a power flow shown by arrows from the input shaft 120 to the output shaft 133 through the gear 104. These arrows are not marked with a reference numeral in FIG. 2 for reasons of clarity.

Overall, it is preferably possible to provide a planetary receiving device 100, which has a possible torsion-free torque transmission allows. In particular, torsion of the bolt elements 122 can be reduced with the planetary receiving device 100.

Further, a method of making a torque transmitting connection of two or more than two components may be provided.
